EMIL M. KNOTHE, OF SEATTLE, WASHINGTON, A-SSIGNOR TO EMELINE KNOTHE, OFSEATTLE, WASHINGTON.

CAR-FENDER.

To all whom t may concern: f

Be it known that I, EMIL M. KNOTHE, a citizen of the United States ofAmerica, and a resident of the city of Seattle, in the county ofKing andState of Washington, have invented certain new and useful Improvementsin Car-Fenders, of which the following is a specification.

My invention relates to fenders for cars or vehicles and moreparticularly to that type which is automatic in operation.

The primary aim is to provide a fender of simple and durableconstruction wherein the operation throughout is eflicient.

Further objects will be set forth in the following specification towhich reference is had, in connection with the accompanying drawings,for a full understanding of the invention, and those features ofconstruction, arrangements and combinations of parts on which I desireprotection will be defined in a succinct manner in the appended claims.

In the drawings, wherein like characters of reference are used todesignate corresponding parts throughout the several views, Figure 1 isa longitudinal fragmentary section of a car embodyingy my invention andshowing two raised positions of my fender in dotted lines. Fig. 2 is asimilar view wherein the fender has been Amoved to trip the operatingmechanism. Fig. 3 is a horizontal section taken below the car platformand having portions broken away for the sake of clearness, and Fig. 4 isa fragmentary front elevation of the car with my invention applied, thefender apron and guard being removed and other portions being omitted.

Referring more particularly to the drawings, the fender apron 1 andguard 2 are supported and suspended by hangers 3 from brackets 4 fixedto the front of the car 5. The fender apron may be folded up against theguard 2 and both, with hangers 3, swung up to the dot and dash linedposition in Fig. 1, whereby access to the draft bar may be obtainedconveniently. In their normal position the hangers are supported on pins6 for swinging downwardly in a receding manner toward the track, whilebraces 7 yieldingly hold the fender in its forward position.

Each brace 7 comprises a tubular section 8 pivoted to the lower endportion of the Specication of Letters Patent.

adjacent hanger;- a section 9 pivoted to the car and slidable within thetubular section;

and a coiled spring 10 normally tending to maintain the brace extendedand thereby hold the fender in its normal position.

The fender hangers are joined by a transverse bar 11 from which extendsrearwardly a link 12 having its rear terminal engaged in a head 13 forlimited sliding movement. A lever 14, supported between its ends, as at15, for swinging, has one terminal pivotally connected to the head 13and its opposite end portion similarly joined to a piston rod 16. Thepiston of the rod 16 operates under fluid pressure in the cylinder 17the limit of movement of said rod being determined by a nut 18, which isconnected for movement therewith by a threaded rod 19, abutting the stop20 fixed to the cylinder.

Fluid is admitted to the cylinder 17 from a suitable source of supply,such as that used for the brake system, through a system of pipes 21, avalve 22 being included in said pipe system to control the flow offluid. To

vrender the operation automatic, valve 22 is each tripper normally bearsagainst a furcated arm 27 of the rock shaft 28 which latter is mountedfor oscillatory movement and provided with a pull arm 29 joined to thelever 30, of valve 22, by a yieldable connection consisting of a spring31 and a link 32.

Briefly, the operation is as follows: The fender, upon striking anobstruction, swings rearwardly against the tension of the springs 10moving the trippers 24 to rock the shaft 28 and consequently open thevalve 22.. Upon rocking the shaft 28, the trippers ride off the arms 27between their furcations which support the trippers (see dotted positionin Fig. 2). Should the travel of the pull arm 29 be in excess of themovement granted the valve lever 30, the yeildable connectiontherebetween lcompensates therefor. During the initial movement of thefender, the link 12 slides in the head 13 to eliminate the additionalenergy necessary to move also the piston in cylinder 17, and therebyrenders the fender more sensitive and practical. As soon as the fluid isadmitted to the cylinder 17, lever 14 is swung carrying with it the head13 until a rigid connection with the link 12 is obtained, whereupon thefender is dropped or swung downwardly as shown in dotted lines in Fig.2.

It is not my intention to limit my invention to the detailed descriptionabove given, except as the prior art may require, such description beingset forth to give a lucid understanding of the preferred embodiment ofthe invention.

Having thus, described my invention, what I claim as new, and desire tosecure by Letters Patent of the United States of America, 1s:--

1. A movable fender, a yieldable support therefor, a tripping mechanismtherefor comprising a pivoted arm and a rod movable with the fender andhaving operative connection with said arm, and means controlled by saidarm to move the fender.

2. A movable fender, a yieldable support therefor, a tripping mechanismtherefor comprising a pivoted arm and a rod secured to the fender andhaving operative connection with said arm, and means controlled by saidarm to move the fender.

8. A movable fender, a yieldable support therefor, a tripping mechanismtherefor comprising a pivoted bifurcated arm, and a rod secured to thefender and having operative connection with said arm below thebifurcated portion thereof, said rod being adapted to enter saidbifurcation after its initial effort, and means controlled by said armto move the fender.

4. A movable fender, a yieldable support therefor, a tripping mechanismtherefor comprising a pivoted arm and a rod movable with the fender andhaving operative connection with said arm, means controlled by said armto move the fender, and a yieldable connection between said means andsaid arm.

5. A movable fender, a yieldable support therefor, a tripping mechanismtherefor comprising a pivoted arm and a rod movable with the fender andhaving operative connection with said arm, means controlled by said armfor moving the fender, and manually operated means for controlling saidfirst means.

6. A pivoted fender, a telescoping springheld support therefor, atransverse shaft, a bifurcated arm secured thereon, a rod secured to thefender, a guide for said rod, the inner end of said rod bearing againstsaid arm below the bifurcation, and adapted to enter said bifurcationafter its initial effort, a second arm secured upon said shaft and meansconnected with said second arm for swinging said fender downward andback.

7. A pivoted fender, a telescoping, spring. held support therefor, atransverse shaft, a bifurcated arm secured thereon, a rod secured to thefender, a guide for said rod, the inner end of said rod bearing againstsaid arm below the bifurcation, and adapted to enter the saidbifurcation after its initial effort, a second arm secured upon saidshaft, means for swinging said fender downward and back, and a yieldableconnection between said means and said second arm.

Signed at Seattle, Washington this 20th day of October 1914.
